J. YEGEN PROCESS FOR REMOVING STUMPS Filed OCb. l1. 1922 ATTORNEYSPatented Ang'. 7, lQZii.

Application filed October ll, 1922.

To NZZ yiff/mm it muy concern:

Be it known that l, JOHN YnGnN, a citi! zen of the United States, and aresident of Bismarck9 in the county oi.i Burleigh and State of NorthDakota, have invented certain new and useful Improvements in Processesfor Removing' Stumps, oi which the following is a specification.

This invention relates to a process for removing' stumps and has i'orits object the provision of a process whereby ya stump is converted intocharcoal.

A further object of the invention is the provision of a process forremoving stumps by displacing the 'soil adjacent the stump to provide alire boX for the reception of iire wood. The stump is bored to providevertii cal air passages extending from the top oli the stump to thespace between the bottom of the stump and the soil. Incompletecombustion orD the stump and wood is had by lighting the wood andcovering the stump and wood with soil whereby the stump is convertedinto charcoal.

Other objects and advantages of the invention will become apparentduring the course of the following description.

The invention is illustrated by way of example in the accompanyingdrawings in which,

Figure 1 is a transverse vertical section of the stump showing the soilremoved to form a fire pit.

Figure 2 is a plan view of the stump disclosing the arrangement of thevertical passages.

Figure 3 is a transverse vertical section of the stump disclosingvertical passages and the rire wood arranged beneath and around thestump.

Referring to the drawings, 1 indicates a stump which is sawed off toform a Hat top 2 about 6 inches from the normal level ofthe ground 3.The soil is removed from the outer wall of the stump as shown at e. Soilalso is removed as shown at 5 which is located below the bottom of thestump and ade jacent the upper end of the roots whereby a spaceisprovided between the side wall of the stump and the earth and betweenthe bottom of the stump and the layer oisoil 6 which forms the base ofthe newly constructed fire pit.

The usual central root of the stump may be shirred 0E in order toprovide a greater Serial No. 593,815.

space between the bottom 6 oit' the tire pit and the base of the stump.

les shown in Figures 2 and 3, a series of vertical passages T are boredthrough the top oit the stump downwardly where the passages open intothe space 5 between the bottom 6 of the fire pit and the bottom of thestump to provide air pas whereby the hotl gases may pass from the lowerporition of the pit upwardly through the stump tor convertingtheI stumpinto charcoal and in a manner which will be presently described. l

ihe stump is now in condition to be packed with re wood. s shown inFigure 3 pieces of' fire wood 9 are packed beneath the stump and in thespace 5 while other fire wood 10 is packed upon the top 2 and around thesides of the stump. The lire wood is then ignited in any suitable nianner a' at least points around the stump in order that a sufficientpartial combustion of the Vlire wood and stump will be had.

"W hen the iire wood` is burning properly boards 11 are placed upon thefirewood 10 and are provided with perorations 12 which are adapted to bealined with vertical )ass-ages in the stump l. The boards and fire woodthen are covered by a coating ot soil 13. i

lt will be necessary from time to time to properly guard the lire inorder to prevent the fire from consuming the stump instead of convertingit into charcoal.

The amount ot fire wood placed about and beneath the stump is su'licientto convert the stump into charcoal. Due to the covering 13 the ifire isnot supplied with su'flicient oxygen to support. complete combustion andtherefore the stump is converted into charcoal. The gases termed by theslow burning of the wood will escape through the if'erticall passages 7and eventually through the cover 13 without creating any great amount ofdraft through said passages,

After the stump and wood have been converted .into charcoal the layer'of soil 13 mav be removed when the charcoal may be readily removed.

llVhat l claim is:

1. The process of removing stumps which consists in removing asuiiicient amount of soil from about the stump to provide a lire pitbetween the outer wall oit the stump and the earth, drilling verticalair passages through the stump to connect the space below the stump withthe atmosphere, then converting the stump into charcoal by burning thestump with an incomplete combustion.

2. The process of removing stumps which consists in removing a suHicientamount of soil from about the stump to provide a lire pit around andbeneath said stump, forming vertical air passages in the stump, fillingthe excavated space about the stump with iire Wood, igniting the fireWood and then covering the fire Wood and stump with soil.

3. The process of removing stumps which consists in removing asufficient amount of soil from about the stump to provide a [ire pitaround and beneath said stump, forming vertical air passages in thestump, covering the top of the stump with fire Wood, ignit- 4ing thefire Wood on all sides or' the stump and then banking the fire withsoil.

4. The process oic removing stumps which consists in removing asufficient amount of soil from about the stump to provide a ire pitaround and beneath said stump, forming vertical air passages in thestump, covering the top of the stump With re Wood, igniting the fireWood on all sides of the stump, covering the top of the stump withperforated boards and then covering the boards, stump and re Wood withsoil.

5. The process of remo-ving stumps which consists in removing asu'ilicient amount of soil from about the stump to provide a re'x pitaround and beneath said stump, forming vertical air passages in thestump, covering` the top of the stump with iire wood7 igniting the lireWood on all sides or' the stump, sawing orf the stump about six inchesfrom the level of the ground, boring vertical air passages directlythrough the stump, packing ire Wood about the sides, beneath the stumpand on the top of the stump7 igniting the fire Wood on all sides of thestump7 and then banking the fire With soil.
